Sudoku Puzzle with Limits
A Puzzle by David Pleacher
Solve the 28 limit problems below and place the answer in the corresponding cell
(labeled A, B, C, … Y, Z, a, b). Your answers should be integers from 1 to 9 inclusive.
Then solve the resulting SUDOKU puzzle.
The rules of Sudoku are simple.
Enter digits from 1 to 9 into the blank spaces.
Every row must contain one of each digit.
So must every column, and so must every 3x3 square.
Each Sudoku has a unique solution that can be reached logically without guessing.
